How about ............. Someone posts a picture - everyone then suggest a caption for it.
The person who comes up with the best caption posts the next picture. We will need a time scale ..........a week?
We will also need to find a way to judge the best.....moderators or some sort of poll?
Had a thought what about the winner is picked by the person posting that pic - I love power ;-)
I will add a pic and caption to start ....(just be careful of copyright)
